Provided is a valve for high-pressure gas, wherein a sheet member is provided inside a through hole formed in a valve body of the valve, wherein the sheet member constitutes a channel for high-pressure gas inside the through hole, wherein the sheet member is fixed inside the through hole by a pressing member, wherein an end opening of the through hole is closed by a lid member, wherein a gasket is provided at a peripheral part of the end opening of the through hole, wherein the gasket is sandwiched between the lid member and the valve body, wherein the lid member is pressed toward the valve body by a plug, and wherein a bearing is provided between the plug and the lid member.

The invention relates to a control valve (10) for a process plant, comprising an actuator (16) which is connected to, and spaced from, a valve body (12) of a valve unit (11) via a yoke (14), the valve body (12) having a housing flange (32) which is detachably connected to the yoke (14), with the valve body (12) having an inlet (20) and an outlet (22) adapted to allow the flow of a process fluid therethrough, which inlet (20) and outlet (22) are each arranged in a fluid connection region (18, 19), and with an actuating member adapted to be displaced by the actuator (16) for controlling the flow rate of the process fluid being arranged in the passage (24) from the inlet (20) to the outlet (22). The invention is characterized in that the housing flange (32) connected to the yoke (14) has at least one recess (44) as well as a yoke fastening region (33), with the yoke fastening region (33) being formed as a bolt hole circle (34) with radially arranged connecting holes (36).

A pressure regulator valve includes: a housing including a base, a cover, and a body; a valve element configured to open and close a valve passage by moving between a closed position and an open position, the valve element being further configured to reduce a primary pressure to a secondary pressure and receive the secondary pressure by which the valve element moves toward the closed position; a biasing unit accommodated in an accommodating space formed between the body and the cover, the biasing unit being configured to bias the valve element such that the valve element moves toward the open position; a first sealing member provided at a gap between the base and the body; and a second sealing member provided a gap between the base and the cover and made of synthetic rubber. The second sealing member is arranged away from the body.

A low-volume non-rising stem gate valve comprising a hollow stem, planetary roller screw and anti-rotation rods. The anti-rotation rods isolate the torque force and maintain the alignment of the planetary roller screw with the stem and the screw shaft, thus reducing the amount of material necessary to support ordinary operational forces.
